The street Lamps LED lamp used in the street lamp lighting advantages
saving electricity: LED lamp energy-efficient, apply for a long time the lighting lamps energy-economizing effect.
save upkeep: LED lighting, long life, high reliability, basic maintenance, can greatly reduce without the lamp maintenance fees.
saving material: the same brightness LED lamp, power, power supply voltage allowed small change. New lamps, small size can approaches the conductor, Station or reduce "transformers" box, and consumption reduced materials and construction cost |
Led with high pressure sodium
lamp Note: the high-pressure sodium lamp is a kind of high efficiency, energy-saving lamps in the road lighting still occupy leading。
